Toyota Prius Plug-in hybrid

How does the Prius Plug-in work?
The Prius Plug-in is what we term a PHEV, or plug-in hybrid electric vehicle. It uses a development of Toyota’s Hybrid Synergy Drive system that combines a rechargeable lithium-ion battery with a 1.8-litre petrol engine to deliver smooth, refined and ultra-efficient driving and incredible economy.

The lithium-ion battery means it can drive approximately 15.5 miles purely on electric power, meaning low running costs and zero emissions.

What is the range of the Prius Plug-in?
The electric-only range of the Prius Plug-in is approximately 15.5 miles, enabling typical commuter journeys to be accomplished with zero tailpipe emissions. Thanks to the hybrid powertrain’s petrol engine, Prius Plug-in is equally able to accomplish long distance trips.

Once the car has reached the limit of its EV driving range, it automatically operates in full hybrid mode, with the petrol engine coming into play. This means there is none of the concern about whether the car can reach its destination without running out of power – the ‘range anxiety’ that is typically associated with full electric vehicles.

Toyota Prius Plug-in hybridHow much does the Toyota Prius Plug-in cost?
Prices for the Toyota Prius Plug-in start at £32,895 on the road, but this falls to £27,895 with the benefit of the £5,000 Government grant available on new plug-in vehicle purchases, provided through the Office for Low Emission Vehicles (OLEV).

What is the CO2 emissions figure of the Prius Plug-in?
The Prius Plug-in achieves a new low benchmark in its class with official CO2 emissions of 49g/km, way below the 100g/km threshold for UK road tax (VED).

What are the fuel consumption figures of the Prius Plug-in?
Official combined mpg figures are 78.5mpg in HV (hybrid vehicle) mode. When you drive solely in EV (electric vehicle) mode, the Prius Plug-in uses no fuel. However, official figures been calculated for EV mode using a standard testing cycle which takes the average from one run with a fully charged battery and a second run with a depleted battery.

Do I need to charge the Prius Plug-in?
Not necessarily. If the Prius Plug-in’s battery is not charged, it simply performs as a ‘standard’ Toyota hybrid vehicle, using the engine and/or the electric motor depending on the driving conditions and battery state of charge.

However, charging the battery does ensure the highest levels of efficiency and zero-emissions driving, particularly in stop-start or low-speed conditions, so we recommend regular charging.

What happens when the EV battery on Prius Plug-in runs out of charge?
The car automaticlaly  switches to HV (hybrid vehicle) mode and runs as a standard Toyota Hybrid, just like the normal Prius.

The Prius Plug-in comes with a dedicated charging cable, which fits under the boot floor. This plugs into a standard domestic socket, but we recommend an isolated charge point is installed to protect against overloading your home’s system.

Luggage capacity above the floor is only 2 litres smaller in the Prius Plug-in than in Prius, at 443 litres (compared with 446 litres for Prius). Below the floor, space is smaller – 40.5 litres vs. 48 litres. Total load volume increases to 1,120 litres when the rear seats are folded.

These figures were measured by the VDA method.

  1. Hi there! Once the hybrid battery is fully charged while driving, does the EV battery start to charge after while braking or going downhill?
    Thank you,

  2. How do we change the “now playing” on our DAB radio, we are listening to one station but it tells us the now playing off of heart FM!?

    1. Hi there,

      Thanks for getting in touch. If you could please provide a VIN number, we will be able to assist you further.


  3. Battery is fully charged, outside temperature is 8 Celsius, driving slightly down the hill, petron engine kicks-in and warms up the engine till I come to work, 3 miles from home. Only 1 mile used electric, other 2 on petrol. Petrol engine starts at 37-39 mpg imperial. Then on electric can drive up to 58 mpg. Why? It happen today at +10 Celsius when I drove back from work when petrol engine cooled down. Dealer at Vantage Leeds said that it must be normal as there are loads of electronics which decide when to do what. The Book says that petrol engine will kick-in when outside temperature is far below Zero Celsius.

    1. Hi Raimondas,

      Thanks for getting in touch. EV driving range takes in a variety of factors including speed, wind resistance, terrain, weight, driving style and much more. The Hybrid system automatically switches between the petrol engine and electric motor to create the most efficient drive. To give you a bit of an indication, on the average urban journey 50% of the driving time is spent in EV mode.

      In addition to this, depending on what car you are driving, it may need a service. In some circumstances if certain filters are not cleaned the engine can run more regularly, however this does depend on the model.


      1. Why ‘The maximum speed in EV mode is 100 km/h (62 mph), or 85 km/h (53 mph) on European models’ is so different? I often drive on motorway 8 miles to my workplace. My PIP does 58 mph on EV. I put cruise control on 57 mph. I watch lorry drivers cursing me and taking over. Should I put banner out saying ‘sorry, this is Toyota Europe…’? Why should I use petrol to please lorry drivers whereas my workplace is within the EV range? Just because Europe decided EV must be below 60 mph? Why non-Europeans are allowed to drive on motorways without causing distress to lorry drivers? Is it a joke or discrimination? Can it be put right? Please change my PIP computer EV top speed number to 62 mph for free, please 🙂

      2. Hi Raimondas,
        Thanks for getting in touch. We are sorry that your Prius Plug-in does not suit your needs.
        We would always recommend checking that the vehicle is suitable, before purchase.
        We have no information about an update to the Prius Plug-in, but the new RAV4 Plug-in will be able to travel in EV mode well above motorway speeds.

  4. I love my prius plug in. Easily the most comfortable and trouble free car I have ever owned. So far 11 years of motoring and with 70 000 + miles on the clock no observable reduction in battery performance. However, why is it that my plug in cable does not seem to fit anywhere other than my home charging point? I have tried all sorts of charging points at service stations, superstores etc.

    1. Hi David, thanks for getting in touch.

      For this question, we advise seeking the help of your nearest Toyota Centre.


    1. Hi Melvin, thanks for getting in touch.
